We want interrupts disabled on all paths leading to RESTORE_ALL;
otherwise, we are risking an IRQ coming between the updates of
alpha_mv->hae_cache and *alpha_mv->hae_register and set_hae()
within the IRQ getting badly confused.

RESTORE_ALL used to play with disabling IRQ itself, but that got
removed back in 2002, without making sure we had them disabled
on all paths.  It's cheaper to make sure we have them disabled than
to revert to original variant...

Remove the detritus left from that commit back in 2002; we used to
need a reload of $0 and $1 since swpipl would change those, but
doing that had become pointless when we stopped doing swpipl in
there...

Thomas Pollet noticed that the remap_file_pages() system call in
fremap.c has a potential overflow in the first part of the if statement
below, which could cause it to process bogus input parameters.
Specifically the pgoff + size parameters could be wrap thereby
preventing the system call from failing when it should.

Add logic to prevent two I/O requests being merged if
only one of them is a discard.  Ditto secure discard.

Without this fix, it is possible for write requests
to transform into discard requests.  For example:

  Submit bio 1 to discard 8 sectors from sector n
  Submit bio 2 to write 8 sectors from sector n + 16
  Submit bio 3 to write 8 sectors from sector n + 8

Bio 1 becomes request 1.  Bio 2 becomes request 2.
Bio 3 is merged with request 2, and then subsequently
request 2 is merged with request 1 resulting in just
one I/O request which discards all 24 sectors.

  arch/tile: remove dead code from intvec_32.S

This "bpt_code" instruction was killed off in our development line a while
ago (the actual definition of bpt_code that is used is in kernel/traps.c)
but I didn't push it for 2.6.36 because it seemed harmless and I didn't
want to try to push more than absolutely necessary.

However, we recently fixed a bug in our gcc that had been causing
"-gdwarf2" not to be passed to the assembler, and passing this flag causes
an erroneous assembler failure in the presence of code in a data section,
sometimes.  While we'd like to track down the bug in the assembler,
we'd also like to make sure 2.6.36 builds with the current toolchain,
so I'm removing this dead code as well.

Thomas Pollet points out that the 'end' variable is broken.  It was
computed based on start/size before they were page-aligned, and as such
doesn't actually match any of the other actions we take.  The overflow
test on end was also redundant, since we had already tested it with the
properly aligned version.

So just get rid of it entirely.  The one remaining use for that broken
variable can just use 'start+size' like all the other cases already did.

Just like pkgtemp registers another core of the same package when one
gets removed, coretemp should register another hyperthread (if
available) in that situation.

As pointed out in the patch fixing the respective code in pkgtemp, the
list protectng mutex must be dropped before calling
coretemp_device_add(), and due to the restructured loop (including an
explicit return) the "safe" variant of the list iterator isn't needed
anymore.

(added device file removal in pkgtemp_remove)

pkgtemp_device_remove(), holding the list protecting mutex, calls
pkgtemp_device_add(), which itself wants to acquire the same mutex.
Holding the mutex over the entire loop body in pkgtemp_device_remove()
isn't really necessary, as long as the loop gets exited after
processing the matched CPU.

Once exiting the loop after removing an eventual match, there's no
need for using the "safe" list iterator anymore.

In commit 0dca94ba the call to
platform_driver_unregister() was made conditional upon !HOTPLUG_CPU,
but the return value from coretemp_init() was left to indicate an
error. This isn't correct, as the negative return value indicates to
the module loader that initialization failed, which isn't intended
here and results in dangling pointers.

This patch fixes the issue which was observed while transfering
a large file ( > 20MB) over USB (OMAP MUSB controller acts as USB host)
to an attached USB thumb drive.

It was found that CDB field of CBW packet was set to 0x0. This was
due to missing a barrier before DMA engine starts transfer.
This  buffer is  allocated using dma_alloc_coherent which gives
non-cacheble but bufferable memory and hence needed a write
memory barrier to flush the write buffer.

This patch fixes one bugs of OUT transfer in double buffer case:

	-the current code only enable autoclear for dma mode 1, and not
	for dma mode 0

Without this patch, test #5 of usbtest can't be passed if we
configure musb as g_zero and use fifo mode 3 to enable double
buffer mode.

With this patch and the following patch(fix dma length),
on my beagle B5, test#5(queued bulk out) may go beyond
18Mbyte/s(seems dma mode 0 is quicker in double buffer case)
if musb is configured as g_zero and fifo mode 3 is taken, follows
the test command:

    #./testusb -D DEV_NAME -c 1024 -t 5 -s 32768 -g 8   [1]

Also I have tested this patch can't make g_ether broken.
